WATER FILTER.y

Application fried November My invent-ion relates to water lilters, andmore particularly to water h'lters connected to down spouts, or drainpipes leading from the gutters of buildings for carrying rain waters tocisterns, sewers and the like, and, itis a distinct andpracticalimprovement to overcome certain practical objections to, anddefect-s in, filters of the character specied. Y

The object of my invention is to provide ay filter casing forinterposition in down drain pipe which is provided Ywith an inletopening, an opposed outlet opening, a lateral foreign matter dischargeopening, anv interior curved screen and a gravity controlled closure forthe lateral opening.

A further object of my invention is to provide a water filter whichpossesses advantages in points of simplicity and efficiency, and, at thesame time proves itself 'comparatively inexpensive in cost ofmanufacture.

With the above and other objects in view, the invention consists in thenovel features of construction, arrangement and combination of partshereinafter more fully described and finally pointed out in the claimhereto appended.

Referring to the accompanying drawings forming a part of thisspecification, wherein like characters of reference denote similar partsthroughout. the several views:

The front wall 7 of the casing 1 is inclined downwardly and outwardlyfrom the top wall of the casing 1 and is provided with a CII suitablefront foreign matter discharge or outlet opening 8. Thefront wall 7 ispro-v vided with an inwardly and downwardly di-v rected splash lip9 atthe upper end of the front outlet opening 8. The front wall 7 vis alsoprovided upon its inner faceV with an angular rest plate 1G which ispositioned a 12, 1925. Serial No. 68,545.

suit-able distance below the lower edge of the opening 8 to provide astop shoulder 11.

Disposed within the casing 1, is a strainer or filter screen 12fhavingits side edges rcinforced bymeans of U-shaped metallic side strips 13.This .screen and its side strips are curved or dished downwardly with.the upper edge ofthe screen in contact with the upper rear corner 14 ofthe y'casing 1 and with its lower edge resting Aupon the angularshapedplate 1() and in contact with the shoulder 11 for firmly butremovably hold.- ing the screen lin position in a curved inclinedposition within the casing' 1, as clearly shown in Fig. 2, so as todirect all foreign matter,vsuch as leaves, bird-nests, and the like thatmay descend through the downpipe 4, out through the lateral or frontopening 8 instead of permitting same to continue through the casing 1and into the lower down-pipe section 4 to find its way into a cistern,sewer, or the like.

The front opening 8 is provided with a suitablel closure 15 having itsside edges flanged or bent inwardly, as at 16, to rein force the sideedges of the closure 15 and to provide a close sliding lit with the sidewall of the casing 1. The upper end of the closure 15 is hingedlyconnectedv to the side walls of the casing 1 by means of a suitablehinge pin 17 passing through openings 18 in the side flanges 16 of theclosure 15and openings 19V in side walls of the casing jl. The lower endof the closure is provided with a suitable finger-*hold 2O for openingthe closure 15 when desired.

The closure 15 is automatically opened by the weight of any foreignmattei' that passes into the casing 1 from the drain pipe t owing to thefact that such foreign matter will slide down the screen 12 and strikethe closure 15 thereby opening the closure 15, as shown in dotted linesin Fig. 2, and permitting of the self'discharge of foreign matter fromwithin the casing 1 through the open ving 8 that may find its wayintothe casing and upon the curved inclined screen 12. rlhe closure 15 willautomatically close itself by gravity due to being hinged at its upperkend andk disposed at a slight angle in its nor# mally kclosed position.

While the foreign matter will be discharged through the lateral or frontopening loo 8, it will be observed that thewater will pass through thescreen 12 and passing out of the casing l through the outlet opening 5.

The many advantages of the herein described invention will readilysuggest themselves to those skilled in the art to which it appertains. Y

I do not wish to be understood as having limited myself to the exactdetails of construction shown and described, but desire to have itunderstood that the invention I have shown'in the drawings is merelyillustrative, as it is manifest that various minor changes may be madein the exact construction and particular arrangement of parts withoutdeparting from the spirit of my invention, hence I reserve the right tomake any suoli changes, or modifications as may fairly fall within thescope of the appended claim when fairly construed.

What 4I claim is: y

In a device of the class described for down spouts, a casing havingfront, back, side, top and bottom walls, an inlet stub pipe connected toand directed upwardly from said top wall, an outlet stub pipe connectedto and directed downwardly from said bottom wall, said front wall beinginclined downwardly and provided with a foreign matter dischargeopening, a closure for said discharge opening7 rearwardly directed sideanges for said closure, a hinge eye formed at the upper end of saidclosure, a hinge pin'supported at its ends by the side walls of thecasing and passing through the hinge eye of the Closure7 a splash lipdirected inwardly and downwardly from the front wall of the casingadjacent the hinge eye of the closure, a rest plate fixed to the innerface of the front wall of the casing adjacent the lower end of thedischarge opening thereof, a. removable screen disposed within thecasing with its lower edge restino' upon said rest plateV and its upperedge in Contact with the inner faces of the rear and upper walls of thecasing to retain the screen in a downwardly inclined curved position andside edge reinforcing plates for said screen.

In testimony whereof, I have hereunto signed my name to thespecification.

OTTO E. SCHULZ.
